Midea air conditioner shows what the PO is faulty

1.Midea's air conditioner appears P0 is: electric control board failure**.

The possible reason is that there is a problem with the power supply of the air conditioner, and the power supply voltage is too low or unstable; If the voltage fluctuation is too large, it is recommended that you report for maintenance directly; The protection of the power module is either a problem of external electrical control or a compressor problem. The fixed speed machine shows p0 generally indicates: continuous current protection for 4 times.

The inverter display P0 generally refers to: IPM module protection. It is recommended to provide professional after-sales door-to-door inspection and maintenance.

Cause analysis: There is a problem with the power supply of the air conditioner, and the power supply voltage is too low or unstable. The voltage fluctuation is too large, causing module protection, and it is recommended to install a voltage regulator.

2. Taking Haier as an example, the air conditioner shows that the P0 fault may be caused by the air conditioner's overcurrent protection, so the air conditioner should be turned off for a period of time before turning it on. 3. Taking Oaks as an example, the air conditioner shows that P0 is the inverter module of the outdoor unit. It is recommended that the user can install a voltage regulator.

Air conditioner, that is, air conditioner, refers to the equipment that regulates and controls the parameters such as temperature, humidity, cleanliness, flow rate and other parameters of the ambient air in the building structure by artificial means. Most of the refrigerants are used to evaporate or condense under the action of the compressor, which causes the evaporation or condensation of the surrounding air to achieve the purpose of changing the temperature and humidity.

Around 1000 B.C., the Persians had invented an ancient air conditioning system, using a wind pole installed on the roof to blow the natural wind from the outside through the cool water and into the room, making the people inside feel cool. In the 19th century, the British scientist and inventor Michael Faraday discovered that compressing and liquefiing a certain gas can freeze air, a phenomenon that occurred when liquefied ammonia evaporated, and his idea was still theoretical.

1. The occurrence of P0 in Midea's air conditioner is: the electric control board is faulty**.

2. Cause analysis: There is a problem with the power supply of the air conditioner, and the power supply voltage is too low or unstable.

3. If the voltage fluctuation is too large, it is recommended to install a voltage regulator for module protection.

- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.

First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.

When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.

The air conditioner is not refrigerated or does not refrigerate.

This problem is most common, and the lack of fluorine in air conditioners is the key.

When the machine is turned on, first touch the trachea and judge it by the temperature.

If it is cold, the speed of the fan may be low.

The inner tube scales and dust are cleaned or replaced.

If the inner tube is not considered cool, the thick tube may be flattened.

The return air temperature is not cool, and then touch the intake air to judge.

The air intake is cold and frosty, and fluoride is added to try again.

If the frost slowly disperses, it is a good decision to lack fluoride.

It is not difficult to see the aging of the press, and the lack of exhaust is the key.

Four-way gas is also commonly judged by fluoride collection.

High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.

The air conditioner will be cool for a while, and it will not be cool for a while, and most of them are high-pressure protection.

If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.

I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.

- Finally, I wish the work to go well, fix the air conditioner as soon as possible, and live a happy ———

Summary. Midea's air conditioner shows P0 fault** may be that the automatic mode is turned on, the voltage may be abnormal, or the indoor coil temperature is too high to cause shutdown protection.

Midea's air conditioner shows P0 fault** may be that the bureau friend has turned on the automatic mode, it may be that the voltage is abnormal, or it can be that the temperature of the indoor tung cavity Huai coil is too high to cause shutdown protection.

1. It may be that the automatic mode is turned on: when the set temperature is close to the room temperature, the machine will stop when the set temperature of the ash is reached in the automatic mode. It creates the illusion of failure when it is turned on and stops, but there is no problem with the actual air conditioner. In this case, it is difficult to build a Zen trap and clear the discussion to switch to other modes as early as possible.

2. It may be that the electric voltage is abnormal: when the voltage is unstable, the compressor will be overcurrent protected, resulting in the situation of P0. In this case, Jianyuan Liang proposed to replace the voltage stabilizing device or contact the after-sales Xiaochangtan to replace the voltage stabilizing device.

3. It may be that the indoor coil temperature is too high, resulting in protective shutdown: when the indoor temperature is 26 degrees and the outdoor temperature is above 20 degrees, the air conditioner cannot heat normally, which is easy to cause protection. In this case, it is recommended to check whether the temperature of the indoor coil is abnormal, and if the file is abnormal, it will be repaired after the after-sales hunger.

4. It may be that the failure of the indoor fan does not blow the air and protects the shutdown: when the outdoor fan fails, it will cause frost. In this case, it is recommended that Yuyou defrost and put the indoor unit into the anti-cold air function.

If the situation persists, it is recommended to send it to the after-sales service or a third-party professional organization for maintenance.

The frequency conversion board has been replaced, and the rear ruler can work for 20 minutes, and the external machine has not been working since the shutdown machine is turned on, and the internal machine has no fault code! What is the original bright sleepy pure reason will not start the external machine.

Hello! The inverter air conditioner is directly powered off when it is turned on, is it burned inside your external unit, hello! There is no way to burn out this one, only you Jianyuan yourself ask a professional air conditioner to deal with it, maybe it was a sudden power outage and was protected by Baozhen, hello!

What is the fault of the inverter air conditioner PO of the United States? Hello dear, the cause of the failure: the electric control board is faulty.

Solution: 1. Midea's inverter air display PO represents IPM module protection. Observe whether the installation of the whole machine meets the requirements of the installation specification and whether the heat dissipation is good.

2. Check whether the system pressure, voltage and external fan speed are normal. 3. Disconnect the whole machine and eliminate the source, and use a multimeter to detect the three-phase winding resistance of the compressor body after the whole machine is finished, and the three-phase resistance is equal to the closed knowledge. 4. Whether there is phase loss, short circuit and leakage fault.

Midea's air conditioner shows Wu Hong"po"This usually indicates a malfunction in the air circulation mode. This is a typical bug** and usually needs to be troubled and fixed accordingly.
